For technical questions, don’t hesitate to call us toll free at 866-590-3533. It employed in electrical energy power system for stepping down the voltage of the system to some protected value which is often provided to low rating meters and relays. copper pads bubbled up. LEDs typically have a power-limiting device (either driver or resistors) in order to prevent LEDs from being overdriven. 2.4v x 700mA does not make 3W per LED - it's only 1.68W. Let's say you have a system with a 6-volt light bulb hooked up to a 6-volt battery.The power output of the light bulb is 100 watts. 48V (e.g. Current transformer which is often referred as CT regulates alternating current i.e on its secondary terminal alternating current is proportional to the value of current on its primary. Anyway do you have any idea what is the issue with my setup? A current transformer is normally used to provide isolated lower current on its secondary terminals. are available, and a constant-voltage power supply wouldn’t be necessary. MathJax reference. In other words, current is the rate of flow of electric charge. Amazingly they did not cause the strip to fail. If you’re building an LED fixture or replacing a constant-current driver, it’s important to verify that the output current and voltage of the driver is compatible with the LEDs’ current and voltage. On the other hand, voltageis the electrical force that drives an electric current between two points. By the way thanks for help, I'm kinda electronics noobie. How is this practice viewed? Try running a series of 3 LEDs, with a 7.5ohm series resistor to see if you get the LEDs to react closer to "datasheet specs. Transformers with High-voltage current are attached to porcelain ceramic or polymer bonded insulators to segregate them from the ground. I don't think that was a good idea, I have tried to use one of my LED string with only 3 LEDs and use it with my 12V 1A driver, it light them for a brief moment and then it went down so I guess that 4V/LED destroyed one or maybe all of them. A constant voltage supply will burn them up if there is no current limiting resistor. Secondary current is dependent upon the voltage in addition to the load resistance. Now I just saw your comment with a link to the supply. In an electrical system, increasing either the current or the voltage will result in higher power. ... Let me know in here & I can help you troubleshoot this problem further, if you like. 2 blue and 2 red may not work well. A flow of electrons forced into motion by voltage is current. When beginning to explore the world of electricity and electronics, it is vital to start by understanding the basics of voltage, current, and resistance. They did get hot enough to begin to melt the solder. In some cases, constant-current drivers matching the voltage and current requirements of both the product and the power source (home, vehicle, etc.) To subscribe to this RSS feed, copy and paste this URL into your RSS reader. Meaningful research in PhD with no publications. Constant-current drivers are used to regulate the amount of current supplied to an LED to maximize LED lifetime. The Overflow #45: What we call CI/CD is actually only CI.
